C#画线并调整表格形状

问题描述

这是我的代码

This is my code

private void panel1_Paint(object sender, PaintEventArgs e)
{
   float[] dashValues = { 2, 5, 2, 5 };
   Pen blackPen = new Pen(Color.Black, 2);
   blackPen.DashPattern = dashValues;
   e.Graphics.DrawLine(blackPen, new Point(panel1.Width, panel1.Height),
                       new Point(0, panel1.Height));
}

并且panel1固定在左，右


this is my problem, when i size this form very slowly the dashes become very close together and don''t leave a gap like it is supposed to

例如在调整大小时
看起来像什么:----

它最终看起来像:----

and panel1 is anchored left,right


this is my problem, when i size this form very slowly the dashes become very close together and don''t leave a gap like it is supposed to

推荐答案

private void panel1_Resize(object sender, EventArgs e)
{
    panel1.Invalidate();
}
